The Logitech Cordless Desktop MX 5000 Laser features a built-in LCD on the keyboard that helps people manage the constant flow of information that has become an inherent part of working with computers. The LCD screen can display e-mail and instant message notifications, favorite playlists and Internet radio stations. And by displaying certain information on the LCD - such as the status of the caps lock and F lock keys, volume levels and mute - the keyboard also alleviates visual clutter that would ordinarily be displayed on the computer monitor.
